Specification of Letters Patent.

Application filed April 13, 1916. Serial No. 90,973.

To all 1r 710m it may concern lie it known that I, CHARLES J. CALLAv lnx, a citizen of the United States, and resident of the city of Attleboro, in the county of'Bristol and State of Massachusetts, have invented certain new and useful improvements in Cuff-Buttons, of which the following is'a specification.

This invention relates to cuff buttons of the class constructed of two members detachably connected together, and the object of this invention is to provide a cufl'I button having4 two members adapted to be readily connected to and disconnected from each other and of a class more particularly designed for retaining soft cuffs, each mem ber ofy the button having two spaced apart heads of a sizeto be retainedin the cuff fabric even when the members are disconnected from each other.

A further object of the invention is the vprovision of a pair of elongated spring arms ing action of the head portion of these arms,

causing them to remain under a given tension even when in their spread position.

With these and other objects in View, the invention consists of certain novel features of construction, 'as willibe more fully described, and particularly pointed out in-the-v appended claims.

ln the accompanying drawings: Figure 1 is a side elevation of my improved se] arable button. Fig. 2 is a central sectional view through the button. Figis a central sectional view through one of the button members, showing the spring arms in full and mounted therein. Fig 4- is a top view of the spring arms spread apart as cut from sheet stock and swaged into ay concave form. Fig. 5 is an edge view of the spring arms in extended position. Fig. 6- is a detail showing a sectional side elevation of the spring arms bent up into operative position` with their edge Walls abutting at a point intermediate their opposite ends. Fig. 7 is a back View of the spring arms in elevation. Fig. 8- is a sectional end view on line 8.-8 of Fig. 6 looking inthe direction of the arrow showing the concavo convex shape of the arms.

Like reference characters indicate like parts throughout the. several views.

Referring tothe drawings the shells of the two opposite button members 10 and 11 are. herein shown as being similarly constructed. Themember 10 ,being provided with a post 12, one end of which is l'spread forming a head 13 with a roundingouter surface 14, the opening 15 through this head into the post member is slightly contracted at its edge forming anv annular shoulder 16 for engaging the head of the spring arms presently\\ described. A.1 plate 17 is rolled onto the V4'outer end of this tube 12 which outer endiis preferably shouldered at 18 toy retain the plate 17 thereon. vAn outer face 1S) of any suitable or ornamental material may be connected to this plate 17v by any suitable means, that shown in the drawing being a plate of gold whose edges are rolled over those of the inner plate 17. The opposite button member 11 is also provided with a tubular post 20 whose inner th' is spread to provide a flange or head 21 and the outer end 23 of the post is reduced, and passed through' an opening in the plate 22 and its edge rolled thereover as at 24. The outer plate of this head is attached by having its edge 2G rolled over that of the inner plate 22. It is found in practice diilicult to provide a separable button of this char-` acter having ball and socketretaining elements that will hold against the strain applied to it,"and is strong and durable in construction and one that will retain its spring and yieldability.

An essential feature of my invention is the construction of a pair of spring arms .27 which are preferably struck from spring sheet stock into the concave form illustrated' i Fig. 1, lsaid arms being connected together by the laterally extending base inember 28 which serves as an anchor or securing port1on for retaining thls base between' the plates ofthe outer head of its cuff member. These opposite arms 27 are drawn up into somewhat of a trough shape or concavo convex in cross section as bc'st illustrated in Fig. 8, their outer surface 29 being circular and when bent up into the form illustrated in Fig. 6 are shaped to fit snugly into the tubular post 20. The free ends of these arms being 'shaped as ai 30 so Patented J une 11,916.

ate ,their opposite ends, which construction supports the arms and greatly 4stiffens their spring action and also effectually ApreventsA the spring of the arms from becoming set by '15 constant bending. These arms when bent up'vinto the position illustrated in F ig. 6 naturally stand open 4Somewhat so that they must be forced' under a slight pressure into thev tube and closed slightly, whereby 20 these' arms are always exerting a spreading tendency against the walls of the tube. -My .improved construction ofoelongated 'spring 'arms'mounted in the tubular post of .one of the members renders the construction tremely strong and durable, the arms are ,mly anchored at one end in the outer head 'd are'l securely protected by the tube rough which they passf*`` Having thus described one illustrative embodiment vof my invention it is understood l that thespecic terms employed are used in a descriptive sense only and are not for the purpose of limitation, the Ascope of the inyvention being `defined by the appended claims.

, I claim;

1.v A separable button comprising two separable members, one provided with a pair of complementa] elongated spring arms con- 40 nected at one end and normally spaced apart at theirv free ends, said ends being shaped to form -a contractible head and means in said arms for supportingeach other against a closing action, the other of said button members being provided with a head receiving opening.

arable -members, one provided with two 2. A separable button comprising two sepspaced apart heads connected by a tubular post, a pair of complemental elongated spring arms mounted in said post and extending beyond one of said heads, the free ends of said arms standing normally apart and shaped to 'form an engaging contractible head, said arms-being :tulcrumed against each other at a point intermediate their op posite ends, the other of said button members being provided with an opening for re ceiving and releasably retaining the head ends of said arms. 3. yA separable cui button comprising a pair of button members, each having an inner and outer head spaced and connected by a tubular post, the opening through the inner head into its vpost having a' contracted 65 neck portion, and a pair of elongated resilient arms fitted into andaextending through l of, X

the 'tubular post of Lne/ppposite member from the outer to and beyond its inner head.l

said projecting ends being normally spaced apart and shaped to form a contractible head to enter vthe said opening in the opposite member to releasably secure said members together. l 4. A separable cud button comprising two separable members, each having anl inner and an outer head spaced apart and connected by a post, one of said members being provided with an opening through its inner head, the stock around said opening forming a contracted neck portion, the post in` the other of said members beingtubular and its outer head having an inner and an outer Wall, a pair of resilient elongated arms connected together and provided with ay Bange at oneend secured between said inner and outer walls-0f said head, said arms fitting closely in and extending through the tubular post and beyond its inner head, the projecting ends of said arms being shaped to form a contraotible head adapted t0 enter the opening in the opposite member to releasably secure said members together.

In testimony whereof I afix my signature.
